Answer:
11.2m
Step-by-step explanation:
Using Pythagoras,
a²+b²=c²
10²+b²=15²
100+b²=225
b²=225-100
b²=125
b=√125
b=11.2m

decimal places.
4 + 9•In x= 15.8
A. x = 3.56
B. x= 0.27
C. x = 3.71
D. x = 2.09
Answer:
C. x = 3.71
Step-by-step explanation:
4 + 9(ln x) = 15.8
Subtract 4 from both sides.
9(ln x) = 11.8
Divide both sides by 9.
ln x = 11.8/9
x = e^(11.8/9)
x = 3.71
4 + 9 • In x = 15.8
x= 3.71

Solve for x. 2x−5=−x+7
Answer:
x = 4
Step-by-step explanation
2x−5+x=−x+7+x
3x−5=7
3x−5+5=7+5
3x=12
x=4
Answer:
x = 4
Step-by-step explanation:
You need to isolate the variable on one side first so that the equation is easier to solve. To do that, add x to both sides to get 2x + x, which is 3x. This gets rid of the -x on the other side and results with the new equation
3x - 5 = 7. Add 5 to both sides to get 3x = 12, then divide both sides by 3 to get x = 4.
You can check your work by plugging in 4 for x.
2(4) - 5 = -(4) + 7
8 - 5 = 3
3 = 3
Therefore, x is equal to 4.

If Maya’s crew paints the platform at a rate of 720 feet per hour, determine how long to the nearest hour it will take them to paint the entire platform. ( read and respond)
Answer:
400/2.5 = 720/x
400x = 720 x 2.5
x = 4.5
Step-by-step explanation:
The required hours it would take to paint the entire platform is given as x/720. Where x is the length of measure of the platform.
What is rate of change?Rate of change is defined as the change in value with rest to the time is called rate of change.
Here,
Maya’s crew paints the platform at a rate of 720 feet per hour,
Let the length of the platform be x,
Now,
Divide the length with the rate, giving the time to paint the complete platform,
Time = length/rate
Time = x / 720
Thus, the required hours it would take to paint the entire platform is given as x / 720. Where x is the length of measure of the platform.

128°52°47°133°81°Step-by-step explanation:
Alternate interior angles are congruent, so you know ...
∠2 = 52°
∠3 = 47°
The sum of angles in a triangle is 180°, so ...
∠5 = 180° -∠2 -∠3 = 180° -52° -47°
∠5 = 81°
Linear pairs are supplementary, so ...
∠1 = 180° -∠2 = 180° -52°
∠1 = 128°
∠4 = 180° -∠3 = 180° -47°
∠4 = 133°
_____
Alternate solution
To find angles 1 and 4, you could also make use of the fact that same-side interior angles are supplementary.
what is the linear equation of a line with a rate of change of -1/2 that passes through the point (0, 4)
Answer:
y = 9/2 (fraction)
Step-by-step explanation:
y = mx+c
m = slope
c =y -intercept
Therefore, the required equation is:
y = 2x + c
Putting the point (0,4) in it as it lies on a line, we get:
4 = -1/2 + c
Therefore:
c = 9/2
So, y = 9/2

A right triangle is formed by the ground, the side of the house and the ladder.
The hypotenuse is the ladder
let the side of the house be h
Using the sine ratio in the right triangle formed, then
sin77° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{h}{22}[/tex] ( multiply both sides by 22 )
22 × sin77° = h , then
h ≈ 21.44 ( to the nearest hundredth )
The ladder reaches 21.44 ft up the side of the house
